     or pharmaceutically acceptable salts thereof, which are inhibitors of PI3K-γ which are useful for the treatment of disorders such as autoimmune diseases, cancer, cardiovascular diseases, and neurodegenerative diseases.

TECHNICAL FIELD

The present invention provides derivatives of aminopyrazme compounds that modulate the activity of phosphoinositide 3-kinases-gamma (PI3Kγ) and are useful in the treatment of diseases related to the activity of PI3Kγ including, for example, autoimmune diseases, cancer, cardiovascular diseases, and neurodegenerative diseases.

BACKGROUND

The phosphoinositide 3-kinases (PI3Ks) belong to a large family of lipid signaling kinases that phosphorylate phosphoinositides at the D3 position of the inositol ring (Cantley, Science, 2002, 296(5573):1655-7). PI3Ks are divided into three classes (class I, II, and III) according to their structure, regulation and substrate specificity. Class I PI3Ks, which include PI3Kα, PI3Kβ, PI3Kγ, and PI3Kδ, are a family of dual specificity lipid and protein kinases that catalyze the phosphorylation of phosphatidylinosito-4,5-bisphosphate (PIP₂) giving rise to phosphatidylinosito-3,4,5-trisphosphate (PIP₃). PIP₃ functions as a second messenger that controls a number of cellular processes, including growth, survival, adhesion and migration. All four class I PI3K isoforms exist as heterodimers composed of a catalytic subunit (p110) and a tightly associated regulatory subunit that controls their expression, activation, and subcellular localization. PI3Kα, PI3Kβ, and PI3Kδ associate with a regulatory subunit known as p85 and are activated by growth factors and cytokines through a tyrosine kinase-dependent mechanism (Jimenez, et al., J Biol Chem., 2002, 277(44):41556-62) whereas PI3Kγ associates with two regulatory subunits (p101 and p84) and its activation is driven by the activation of G-protein-coupled receptors (Brock, et al., J Cell Biol., 2003, 160(1):89-99). PI3Kα and PI3Kβ are ubiquitously expressed. In contrast, PI3Kγ and PI3Kδ are predominantly expressed in leukocytes (Vanhaesebroeck, et al., Trends Biochem Sci., 2005, 30(4):194-204).

Expression of PI3Kγ is mainly restricted to hematopoietic system, although it can be also detected at lower level in endothelium, heart and brain. PI3Kγ knockout or kinase dead knock in mice are normal and fertile and do not present any overt adverse phenotypes. Analysis at the cellular level indicates that PI3Kγ is required for GPCR ligand-induced PtdINs (3,4,5)P3 production, chemotaxis and respiratory burst in neutrophils. PI3Kγ-null macrophages and dendritic cell exhibit reduced migration towards various chemoattractants. T-cells deficient in PI3Kγ show impaired cytokine production in response to anti-CD3 or Con A stimulation. PI3Kγ working downstream of adenosine A3A receptor is critical for sustained degranulation of mast cells induced by FCεRI cross-linking with IgE. PI3Kγ is also essential for survival of eosinophils (Ruckle et al., Nat. Rev. Drug Discovery, 2006, 5, 903-918) Given its unique expression pattern and cellular functions, the potential role of PI3Kγ in various autoimmune and inflammatory disease models has been investigated with genetic and pharmacological tools. In asthma and allergy models, PI3Kγ^(−/−) mice or mice treated with PI3Kγ inhibitor showed a defective capacity to mount contact hypersensitivity and delayed-type hypersensitivity reactions. In these models, PI3Kγ was shown to be important for recruitment of neutrophils and eosinopohils to airways and degranulation of mast cells (see e.g. Laffargue et al., Immunity, 2002, 16, 441-451; Prete et al., The EMBO Journal, 2004, 23, 3505-3515; Pinho et al., L. Leukocyte Biology, 2005, 77, 800-810; Thomas et al., Eur. J. Immunol. 2005, 35, 1283-1291; Doukas et al., J. Pharmacol. Exp Ther. 2009, 328, 758-765).

In two different acute pancreatitis models, genetic ablation of PI3Kγ significantly reduced the extent of acinar cell injury/necrosis and neutrophil infiltration without any impact on secretive function of isolated pancreatic acini (Lupia et al., Am. J. Pathology, 2004, 165, 2003-2011). PI3Kγ^(−/−) mice were largely protected in four different models of rheumatoid arthritis (CIA, α-CII-IA, K/BxN serum transfer and TNF transgenic) and PI3Kγ inhibition suppressed the progression of joint inflammation and damage in the CIA and α-CII-IA models (see e.g., Camps et al., Nat. Medicine, 2005, 11, 939-943; Randis et al., Eur. J. Immunol, 2008, 38, 1215-1224; Hayer et al., FASB J., 2009, 4288-4298). In the MRL-lpr mouse model of human systemic lupus erythematous, inhibition of PI3Kγ reduced glomerulonephritis and prolonged life span (Barber et al., Nat. Medicine, 2005, 9, 933-935).

There is evidence suggesting that chronic inflammation due to infiltration by myeloid-derived cells is a key component in the progression of neurodegeneration diseases, such as Alzheimer's disease (AD) (Gin et al., Am. J. Physiol. Cell Physiol., 2005, 289, C264-C276; El Khoury et al., Nat. Med., 2007, 13, 432-438). In line with this suggestion, PI3Kγ inhibition was shown to attenuate Aβ(1-40)-induced accumulation of activated astrocytes and microglia in the hippocampus and prevent the peptide-induced cognitive deficits and synaptic dysfunction in a mouse model of AD (Passos et al., Brain Behav. Immun. 2010, 24, 493-501). PI3Kγ deficiency or inhibition also was shown to delay onset and alleviate symptoms in experimental autoimmune encephalomyelitis in mice, a mouse model of human multiple sclerosis, which is another form of neurodegeneration disease (see e.g., Rodrigues et al., J. Neuroimmunol. 2010, 222, 90-94; Berod et al., Euro. J. Immunol. 2011, 41, 833-844; Comerford et al., PLOS one, 2012, 7, e45095; Li. et al., Neuroscience, 2013, 253, 89-99).

Chronic inflammation has been formally recognized as one of the hallmarks for many different types of cancers. Accordingly, selective anti-inflammatory drugs represent a novel class of anti-cancer therapies (Hanahan and Weinberg, Cell, 2011, 144, 646-674). Since PI3Kγ is reported to mediate various inflammatory processes, its role as an immune oncology target has also been investigated. A recent study reported that PI3Kγ deficiency suppressed tumor growth in the syngeneic models of lung cancer, pancreatic cancer and melanoma (LLC, PAN02 and B16). PI3Kγ deficiency or inhibition also inhibited tumor growth in a spontaneous breast cancer model (Schmid et al., Cancer Cell, 2011, 19, 715-727). A further study reported that PI3Kγ deficiency could ameliorate inflammation and tumor growth in mice having colitis-associated colon cancer, (Gonzalez-Garcia et al., Gastroenterology, 2010, 138, 1373-1384). Detailed mechanistic analysis indicates that tumor infiltration by CD11b⁺ myeloid cells can cause protumorigenic inflammation at tumor sites and PI3Kγ in the myeloid cells is critical in mediating signaling of various chemoattractants in bring the cells to the tumor (Schmid et al., Cancer Cell, 2011, 19, 715-727). Other studies suggest that PI3Kγ is also required for differentiation of naïve myeloid cells into M2 macrophages at tumor sites. M2 macrophages promote tumor growth and progression by secreting immunosuppressive factors such arginase 1, which depletes the tumor microenvironment of arginine, thereby promoting T-cell death and NK cell inhibition (Schmidt et al., Cancer Res. 2012, 72 (Suppl 1: Abstract, 411; Kaneda et al., Cancer Res., 74 (Suppl 19: Abstract 3650)).

In addition to its potential role in promoting protumorigenic microenvironment, PI3Kγ may play a direct role in cancer cells. PI3Kγ is reported to be required for signaling from the Kaposi's sarcoma-associated herpevirus encoded vGPCR oncogene and tumor growth in a mouse model of sarcoma (Martin et al., Cancer Cell, 2011, 19, 805-813). PI3Kγ was also suggested to be required for growth of T-ALL (Subramanjam et al., Cancer Cell, 2012, 21, 459-472), PDAC and HCC cells (Falasca and Maffucci, Frontiers in Physiology, 2014, 5, 1-10). Moreover, in a survey of driver mutations in pancreatic cancer, PI3Kγ gene was found to contain second highest scoring predicted driven mutation (R839C) among the set of genes not previously identified as a driver in pancreatic cancer (Carter et al., Cancer Biol. Ther. 2010, 10, 582-587).

Finally, PI3Kγ deficiency also has been reported to offer protection to experimental animals in different cardiovascular disease models. For examples, lack of PI3Kγ would reduce angiotensin-evoked smooth muscle contraction and, therefore, protect mice from angiotensin-induced hypertension (Vecchione et al., J. Exp. Med. 2005, 201, 1217-1228). In rigorous animal myocardial infarction models, PI3Kγ inhibition provided potent cardioprotection, reducing infarct development and preserving myocardial function (Doukas et al., Proc. Natl. Acad. Sci. USA, 2006, 103, 19866-19871).

For these reasons, there is a need to develop new PI3Kγ inhibitors that can be used for the treatment of diseases such as cancer, autoimmune disorders, and inflammatory and cardiac diseases. This application is directed to this need and others.

One having ordinary skill in the art will appreciate that this embodies compositions containing about 500 to about 550, about 550 to about 600, about 600 to about 650, about 650 to about 700, about 700 to about 750, about 750 to about 800, about 800 to about 850, about 850 to about 900, about 900 to about 950, or about 950 to about 1000 mg of the active ingredient.

Similar dosages may be used of the compounds described herein in the methods and uses of the disclosure.

The active compound can be effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.

For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present disclosure. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, for example, about 0.1 to about 1000 mg of the active ingredient of the present disclosure.

The tablets or pills of the present disclosure can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.

The liquid forms in which the compounds and compositions of the present disclosure can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.

Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions can be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device can be attached to a face mask, tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices which deliver the formulation in an appropriate manner.

Topical formulations can contain one or more conventional carriers. In some embodiments, ointments can contain water and one or more hydrophobic carriers selected from, for example, liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white Vaseline, and the like. Carrier compositions of creams can be based on water in combination with glycerol and one or more other components, e.g. glycerine monostearate, PEG-glycerine monostearate and cetylstearyl alcohol. Gels can be formulated using isopropyl alcohol and water, suitably in combination with other components such as, for example, glycerol, hydroxyethyl cellulose, and the like. In some embodiments, topical formulations contain at least about 0.1, at least about 0.25, at least about 0.5, at least about 1, at least about 2, or at least about 5 wt % of the compound of the disclosure. The topical formulations can be suitably packaged in tubes of, for example, 100 g which are optionally associated with instructions for the treatment of the select indication, e.g., psoriasis or other skin condition.

The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration, and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient, and the like.

The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers, or stabilizers will result in the formation of pharmaceutical salts.

The therapeutic dosage of a compound of the present disclosure can vary according to, for example, the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the disclosure in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the disclosure can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 μg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.

The compositions of the disclosure can further include one or more additional pharmaceutical agents such as a chemotherapeutic, steroid, anti-inflammatory compound, or immunosuppressant, examples of which are listed herein.

Labeled Compounds and Assay Methods

Another aspect of the present disclosure relates to labeled compounds of the disclosure (radio-labeled, fluorescent-labeled, etc.) that would be useful not only in imaging techniques but also in assays, both in vitro and in vivo, for localizing and quantitating PI3K in tissue samples, including human, and for identifying PI3K ligands by inhibition binding of a labeled compound. Substitution of one or more of the atoms of the compounds of the present disclosure can also be useful in generating differentiated ADME (Adsorption, Distribution, Metabolism and Excretion) Accordingly, the present disclosure includes PI3K assays that contain such labeled or substituted compounds.

The present disclosure further includes isotopically-labeled compounds of the disclosure. An “isotopically” or “radio-labeled” compound is a compound of the disclosure where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (i.e., naturally occurring). Suitable radionuclides that may be incorporated in compounds of the present disclosure include but are not limited to ²H (also written as D for deuterium), ³H (also written as T for tritium), ¹¹C, ¹³C, ¹⁴C, ¹³N, ¹⁵N, ¹⁵O, ¹⁷O, ¹⁸O, ¹⁸F, ³⁵S, ³⁶Cl, ⁸²Br, ⁷⁵Br, ⁷⁶Br, ⁷⁷Br, ¹²³I, ¹²⁴I, ¹²⁵I and ¹³¹I. For example, one or more hydrogen atoms in a compound of the present disclosure can be replaced by deuterium atoms (e.g., one or more hydrogen atoms of a C₁₋₆ alkyl group of Formula (I) can be optionally substituted with deuterium atoms, such as —CD₃ being substituted for —CH₃). In some embodiments, alkyl groups of the disclosed Formulas (e.g., Formula (I), (II), etc.), can be perdeuterated.

One or more constituent atoms of the compounds presented herein can be replaced or substituted with isotopes of the atoms in natural or non-natural abundance. In some embodiments, the compound includes at least one deuterium atom. For example, one or more hydrogen atoms in a compound presented herein can be replaced or substituted by deuterium (e.g., one or more hydrogen atoms of a C₁₋₆ alkyl group can be replaced by deuterium atoms, such as —CD₃ being substituted for —CH₃). In some embodiments, the compound includes two or more deuterium atoms. In some embodiments, the compound includes 1, 1-2, 1-3, 1-4, 1-5, or 1-6 deuterium atoms. In some embodiments, all of the hydrogen atoms in a compound can be replaced or substituted by deuterium atoms.

In some embodiments, 1, 2, 3, 4, 5, 6, 7, or 8 hydrogen atoms, attached to carbon atoms of any alkyl, alkenyl, alkynyl, aryl, phenyl, cycloalkyl, heterocycloalkyl, or heteroaryl substituents, or —C₁₋₆ alkyl-, alkylene, alkenylene, and alkynylene linking groups, as described herein, are each optionally replaced by a deuterium atom.

Synthetic methods for including isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas (New York, N.Y., Appleton-Century-Crofts, 1971; The Renaissance of H/D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of Chemistry, 2011). Isotopically labeled compounds can be used in various studies such as NMR spectroscopy, metabolism experiments, and/or assays.

Substitution with heavier isotopes, such as deuterium, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances, (see e.g., A. Kerekes et.al. J. Med. Chem. 2011, 54, 201-210; R. Xu et.al. J. Label Compd. Radiopharm. 2015, 58, 308-312). In particular, substitution at one or more metabolism sites may afford one or more of the therapeutic advantages.

The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. For example, for in vitro PI3K labeling and competition assays, compounds that incorporate ³H, ¹⁴C, ⁸²Br, ¹²⁵I, ¹³¹I or ³⁵S can be useful. For radio-imaging applications ¹¹C, ¹⁸F, ¹²⁵I, ¹²³I, ¹²⁴I, ¹³¹I, ⁷⁵Br, ⁷⁶Br or ⁷⁷Br can be useful.

It is understood that a “radio-labeled” or “labeled compound” is a compound that has incorporated at least one radionuclide. In some embodiments the radionuclide is selected from the group consisting of ³H, ¹⁴C, ¹²⁵I, ³⁵S and ⁸²Br.

The present disclosure can further include synthetic methods for incorporating radio-isotopes into compounds of the disclosure. Synthetic methods for incorporating radio-isotopes into organic compounds are well known in the art, and an ordinary skill in the art will readily recognize the methods applicable for the compounds of disclosure.

A labeled compound of the disclosure can be used in a screening assay to identify/evaluate compounds. For example, a newly synthesized or identified compound (I.e., test compound) which is labeled can be evaluated for its ability to bind a PI3K by monitoring its concentration variation when contacting with the PI3K, through tracking of the labeling. For example, a test compound (labeled) can be evaluated for its ability to reduce binding of another compound which is known to bind to a PI3K (i.e., standard compound). Accordingly, the ability of a test compound to compete with the standard compound for binding to the PI3K directly correlates to its binding affinity. Conversely, in some other screening assays, the standard compound is labeled and test compounds are unlabeled. Accordingly, the concentration of the labeled standard compound is monitored in order to evaluate the competition between the standard compound and the test compound, and the relative binding affinity of the test compound is thus ascertained.

Kits

The present disclosure also includes pharmaceutical kits useful, for example, in the treatment or prevention of PI3K-associated diseases or disorders, such as cancer, which include one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of the disclosure. Such kits can further include, if desired, one or more of various conventional pharmaceutical kit components, such as, for example, containers with one or more pharmaceutically acceptable carriers, additional containers, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and/or guidelines for mixing the components, can also be included in the kit.

The invention will be described in greater detail by way of specific examples. The following examples are offered for illustrative purposes, and are not intended to limit the invention in any manner. Those of skill in the art will readily recognize a variety of non-critical parameters which can be changed or modified to yield essentially the same results. The compounds of the Examples have been found to be PI3Kγ inhibitors according to at least one assay described herein.

EXAMPLES

Preparatory LC-MS purifications of some of the compounds prepared were performed on Waters mass directed fractionation systems. The basic equipment setup, protocols, and control software for the operation of these systems have been described in detail in the literature (see e.g. “Two-Pump At Column Dilution Configuration for Preparative LC-MS”, K. Blom, J. Combi. Chem., 4, 295 (2002); “Optimizing Preparative LC-MS Configurations and Methods for Parallel Synthesis Purification”, K. Blom, R. Sparks, J. Doughty, G. Everlof, T. Haque, A. Combs, J. Combi. Chem., 5, 670 (2003); and “Preparative LC-MS Purification: Improved Compound Specific Method Optimization”, K. Blom, B. Glass, R. Sparks, A. Combs, J. Combi. Chem., 6, 874-883 (2004)).

The compounds separated were typically subjected to analytical liquid chromatography mass spectrometry (LCMS) for purity analysis under the following conditions: Instrument=Agilent 1100 series, LC/MSD; Column: Waters Sunfire™ C₁₈ 5 μm, 2.1×50 mm, Buffers: mobile phase A: 0.025% TFA in water and mobile phase B: acetonitrile; gradient 2% to 80% B in 3 minutes with flow rate 2.0 mL/minute.

Some of the compounds prepared were also separated on a preparative scale by reverse-phase high performance liquid chromatography (RP-HPLC) with MS detector or flash chromatography (silica gel) as indicated in the Examples. Typical preparative reverse-phase high performance liquid chromatography (RP-HPLC) column conditions are as follows:

pH=2 purifications: Waters Sunfire™ C₁₈ 5 μm, 30×100 mm or Waters XBridge™ C₁₈ 5 μm, 30×100 mm column, eluting with mobile phase A: 0.1% TFA (trifluoroacetic acid) in water and mobile phase B: acetonitrile; the flow rate was 60 mL/minute, the separating gradient was optimized for each compound using the Compound Specific Method Optimization protocol as described in the literature (see e.g., “Preparative LCMS Purification: Improved Compound Specific Method Optimization”, K. Blom, B. Glass, R. Sparks, A. Combs, J. Comb. Chem., 6, 874-883 (2004)).

pH=10 purifications: Waters XBridge™ C₁₈ 5 μm, 30×100 mm column, eluting with mobile phase A: 0.1% NH₄OH in water and mobile phase B: acetonitrile; the flow rate was 60 mL/minute, the separating gradient was optimized for each compound using the Compound Specific Method Optimization protocol as described in the literature (see e.g., “Preparative LCMS Purification: Improved Compound Specific Method Optimization”, K. Blom, B. Glass, R. Sparks, A. Combs, J. Comb. Chem., 6, 874-883 (2004)).

Stereochemical Rationale

The Sharpless asymmetric dihydroxylation of olefins has been studied extensively, and its basis as a model for enantioselectivity is well established (Sharpless, K. B.; Amberg, W.; Bennani, Y. L.; Crispino, G. A.; Hartung, J.; Jeong, K.-S.; Kwong, H.-L.; Morikawa, K.; Wang, Z.-M.; Xu, D.; Zhang, X.-L. J. Org. Chem., 1992, 57, 2768-2771; and Kolb, H. C.; VanNieuwenhze, M. S.; Sharpless, K. B. Chem. Rev., 1994, 94, 2483-2547). Briefly, the application of AD-mix-α (containing (DHQ)₂-PHAL) in the dihydroxylation of prop-1-en-2-ylbenzene affords (S)-2-phenylpropane-1,2-diol. Application of AD-mix-β (containing (DHQD)₂-PHAL) in the dihydroxylation of prop-1-en-2-ylbenzene affords (A)-2-phenylpropane-1,2-diol (Sharpless and Kolb, supra). Moreno-Dorado et al. extended the method to the trifluoromethyl case (e.g., (3,3,3-trifluoroprop-1-en-2-yl)benzene affords (S)-3,3,3-trifluoro-2-phenylpropan-1,2-diol when treated with AD-mix-α and affords (A)-3,3,3-trifluoro-2-phenylpropane-1,2-diol when treated with AD-mix-β), and the stereochemical outcome was verified by subsequent conversion to well known compounds whose specific rotations were found to be in agreement with the literature values (Moreno-Dorado, F. J.; Guerra, F. M.; Ortega, M. J.; Zubia, E.; Massanet, G. M. Tetrahedron: Asymmetry, 2003, 14, 503-510). While not wishing to be bound by any one theory, in the dihydroxylations performed on vinyl arenes in the examples, we expect to obtain the (S)-configuration with AD-mix-α and the (R)-configuration with AD-mix-β.

Example 1. 3-Amino-6-(5-(3-amino-1,1,1-trifluoro-2-hydroxy-3-oxopropan-2-yl)-2-methylphenyl)-N-(2-hydroxy-2-methylpropyl)pyrazine-2-carboxamide

A solution of 3-bromo-4-methylbenzaldehyde (6.51 g, 32.7 mmol) [Combi-Blocks, HC-3454] in dry tetrahydrofuran (65.4 mL) was cooled to 0° C. followed by the addition of trimethyl(trifluoromethyl)silane (6.28 mL, 42.5 mmol). The yellow mixture was treated with 1.0 M tetra-n-butylammonium fluoride in tetrahydrofuran (0.654 mL, 0.654 mmol) at 0° C. and stirred for a few minutes at 0° C. The ice bath was removed and the resulting reaction mixture was stirred for 1.5 h. The reaction mixture was cooled back to 0° C. and treated with water (6.48 mL, 360 mmol) and 1.0 M tetra-n-butylammonium fluoride in tetrahydrofuran (6.54 mL, 6.54 mmol).

The reaction mixture was concentrated (by rotary evaporation with the water bath set at 30° C.) to an oily solid that was diluted with diethyl ether (200 mL) which precipitated more solids. This mixture was filtered over Celite® and the Celite® was rinsed with additional diethyl ether (200 mL). The filtrate was washed with saturated sodium bicarbonate solution (3×200 mL) and brine, dried over sodium sulfate, filtered, and concentrated to give an oily solid. The oily solid was partitioned between diethyl ether (150 mL) and water (100 mL). The organic layer was separated and washed with saturated sodium bicarbonate solution (2×75 mL) and brine, dried over sodium sulfate, filtered, and concentrated to give the desired product (7.93 g, 95.0%) as an oil that was used without further purification.

The combined organic extracts were washed with brine, dried over sodium sulfate, filtered, and concentrated to give a brown oil. Purification by flash column chromatography using MTBE in hexanes (0% to 60%) gave the desired product as a yellow oily solid. The racemic mixture was separated via preparative chiral HPLC (Phenomenex Lux Amylose-1 [21.2×250 mm, 5 micron], eluting with 95% ethanol in hexanes, at flow rate of 18 mL/min, loading about 100 mg in 2 mL ethanol) to give the desired second eluting enantiomer (4.50 g, 48.8%) as a viscous yellow oil.
